Senate Advances $1.1B Zika Proposal Amid Clash With House Over Funding

The chambers are divided on how much should be allocated to combat the virus.

— -- The House has passed a $622 million Zika funding measure along party lines Wednesday night, ignoring President Obama’s veto threat and putting the lower chamber on a collision course with the Senate and White House over how to best fight the spread of the Zika virus.

The measure -- about a third of President Obama's $1.9 billion Zika funding request -- will have to be reconciled with the Senate's own Zika package before heading to the White House for President Obama's signature.

The Senate's bipartisan proposal, a $1.1 billion anti-Zika amendment to a military spending bill, is expected to pass Thursday morning.

Sen. Patty Murray, D-Washington, who crafted the deal with Sen. Roy Blunt,R-Missouri, took to the Senate floor Tuesday to stress the urgency of getting one of the billion-dollar packages to the president’s desk, which the senators hope will extend the funding through the end of the next fiscal year in June 2017.

She also said the House package -- which would provide $622 million for use over the next five months -- is far too little.

“House Republicans have released a proposal that would provide a very meager $622 million dollars -- less than a third of what is needed for this emergency without any funding for preventive health care or outreach to those at risk to Zika,” she said.

Rep. Hal Rogers, the chairman of the House Appropriations Committee who led the drafting of the House proposal, defended his package by saying the administration did not provide enough information about where the money would be allocated, so his panel only funded immediate efforts, with the understanding that it would revisit the issue at the end of the funding period. The administration’s request for Zika mirrors the request made for Ebola last year. Health officials told ABC News they need flexibility to move money around quickly as the threat evolves.

The House package -- which President Obama has threatened to veto -- includes $350 million in unobligated funds that were originally supposed to combat the Ebola crisis.

“This legislation will make dollars available to fight the disease now, prioritizing critical activities that must begin immediately, such as vaccine development and mosquito control. The legislation funds these efforts in a responsible way, using existing resources -- including excess funding left over from the Ebola outbreak -- to pay for it,” Rogers said in a statement.

But Democrats and the Department of Health and Human Services argues that moving the money away from Ebola efforts could imperil the ability to respond to a resurgence in that disease.

“We cannot Rob from Peter to pay Paul,” Rep. Sheila Jackson Lee, D-Texas, bellowed on the House floor Wednesday evening.

The House Republican proposal is offset with spending cuts to other federal programs, while the Senate and White House proposals would add to the budget deficit.
